Loading steamlib.so on Ubuntu 22, it works when running in the PB IDE, but when generating the executable and run, it gives an error when importing the library.

Ubuntu 22.04.2 x64
Source PB + Libraries Linux64 : https://filebin.net/25ye4q13vvb7b8iw

What could be happening that doesn't find steamlib.so in the same folder?

If the lib is not in the standard folder, but in the same folder as program, you must also specify the path.

Code: Select all

Macro GetProgramPath()
  GetPathPart(ProgramFilename())
EndMacro

libPath.s = GetProgramPath() + "steamlib.so"

Debug libPath

What could be happening?

Strange ...

I'll have to test it tonight.
What if the files are on the Linux drive and not on the Parallels shared folder?

I have localised the problem.

When the program is started from the PureBasic IDE, the debugger creates its own environment with the search path of the executable.

Without the debugger there is not this path.
but the steamlib.so has a dependency to the libsteam_api.so and does not find it.

Terminal:

ldd steamlib.so
linux-vdso.so.1 (0x00007fffc2beb000)
libsteam_api.so => not found
libstdc++.so.6 => /lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007df8dda00000)
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007df8ddddb000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007df8dd600000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007df8ddcf4000)
/lib64/ld-linux-x86-64.so.2 (0x00007df8dde24000)

If you put the libsteam_api.so in the path /usr/lib the programme works, because the steamlib.so then finds the library libsteam_api.so.

You can try adding the directory with the libraries to the LD_LIBRARY_PATH environment variable before loading the lib. This might help.

The IDE modifies this variable too but it only adds the PB compiler directory to it nothing else so I am not sure if this is what makes the difference.

So the problem is with SteamworksPy https://github.com/philippj/SteamworksPy, which is forcibly searching in the /usr/lib folder?

using command : SetEnvironmentVariable(Name$, Value$) ??

Yes. This is the IDE code: https://github.com/fantaisie-software/p ... e.pb#L1796

Not work with set 'LD_LIBRARY_PATH'

where created the steamlib.so ?

I compiled it as the documentation instructs.
Could it be something directly in the SteamworksPy code?

Source Code used : https://github.com/philippj/SteamworksP ... /tag/1.6.5
compile documentation [Linux] : https://philippj.github.io/SteamworksPy/

Posted: **Tue Jun 25, 2024 7:30 pm**

Looks like I found something that might help. https://github.com/philippj/SteamworksPy/issues/61
If it works, my theory was correct, which was something with the code/compilation xD

UPDATE : fixed that with adding to the end of makefile: -Wl,-rpath=. :
g++ -std=c++11 -o SteamworksPy.so -shared -fPIC SteamworksPy.cpp -l steam_api -L. -Wl,-rpath=.

Thank you so much for your help, mk-soft & freak. You guys are awesome!
